Clinical Trial Summary

Phase II Pilot Study of Trastuzumab Biosimilar (Herzuma®) plus Gedatolisib in Patients with HER-2 Positive Metastatic Breast Cancer Who Progressed after 2 or more HER-2 directed Chemotherapy


Description:

All the patients will be included in the final analysis, with a total of 15 patients to be enrolled. Treatment will occur until disease progression, unacceptable toxicity or patient withdrawal. Tumor measurement and evaluation are going to be performed at every 6 weeks for the first 3 months, then at every 9 weeks till progression, and then follow-up evaluation at every 12 weeks thereafter end of study.

Eligibility Inclusion Criteria: - Breast tumor with suspected PI3K-pathway dependence (either by mutation or by known biologic rationale. PI3K dependence includes the presence of a PIK3CA-mutant hotspot mutation, PIK3CA copy number gain, mTOR hotspot mutation, or PTEN loss in the archival or fresh tumor tissue specimen identified in K-MASTER panel.
